I am able to install Oracle VB versions 6 and 7 on "Windows 11 Pro", however, when trying to add Host-Only Network it is throwing below error:

Code: Select all

1. Uninstall Virtualbox and reboot.
2. Go to "C:\Windows\System32\drivers", look for any files called 'Vbox*.sys' (there could be up to 5) and delete them.
3. Reboot again.
4. If you have any 3rd-party security or anti-malware software, disable the living daylights out of it for a moment.
5. Reinstall Virtualbox using right-click-Run-As-Administrator.
